Hi Rich,
The software for my eprom programmer can split files relatively easy.
Download the PEP software from
www.arlabs.comIt runs in DOS mode. Runs fine on Windows XP.
Press "C" a few times to Continue, the programmer will complain that the programmer unit is not connected.
Select an EPROM (won't make a difference, but if you select the right size the later save defaults will be correct)
Press "4" to "Read Disk File into Buffer"
Once in this sub-menu, press "4" again to select "16/32 Bit Data"
Then select "Word" and choose which bytes you want to load the buffer with, Even or Odd.
This will split the file as it's read in.
Now choose "A" from the main menu to save Buffer to disk file, there's your first even or odd file. Repeat for the odd bytes.
You can choose "5" to view the buffer.
Hope this helps,
Josh

Subject: [N8VEM-S100:5482] MSDOS Support Board V2 questions
From:
rich...@verizon.netTo:
n8vem...@googlegroups.comAll —
I just finished assembling the board, testing as much stuff along the way as I could with the Z80 board. Things seem to work fine, but I have a few clarifying questions. I hope to use this board, initially, as a proxy for the Seattle Computer Products CPU Support Board as part of a system re-creation/demo project I’m working on. I have the SCP-200B 8086 board, the Cromemco 16FDC, an SSM IO4 (console card) and a CompuPro RAM22 (which subs for several SCP 16k memory boards). I hope this will approximate the system Tim Paterson used to create 86-DOS.
Here are my questions:
- The EEPROM configuration and test procedures for the V2 board mention jumpering K1. There is no K1 on the V2 schematic or on the board (that I can find). Is this a typo? I found all of the other jumpers in that procedure.
- Jumper setting for K5 isn't mentioned in the procedures (assuming not jumpered).
- Jumper setting for JP6 (4.7k pull-up on the board select line) also isn’t mentioned (assuming not jumpered).
- Default jumpering for P39/P37/P53 (VI settings for the RTC). Assuming not used.
- How are people connecting the keyboard interrupt (P54.15) to VI1 (P54.4)? I would assume wire wrap wire but I wanted to check. Important for MSDOS.
Are there any other gotchas I should be aware of? Thanks!
Rich
